Have you ever noticed it's always a very nice day the day after a big front blows through town? I sure have and Sunday was absolutely gorgeous. Don't think it's just a coincidence because there is something to it. The day after a big front the air is usually fresh, drier and cleaned out. The sky is deeper blue and the sunsets more fantastic since the visibility is less restricted due to lower moisture content. And on top of that the air seems to have an exhilarating smell that makes you want to get outside and breath it all in.
I hope you got a chance to enjoy Sunday because things are going to go downhill again in the weather department soon. We continue in a stormy weather pattern with a long wave trough of low pressure in the upper levels of the atmosphere established to our west sending smaller waves of low pressure we call short waves through the flow into the southern plains with rounds of stormy weather.
This pattern this time of year is literally a drought buster! The state of Oklahoma has received unprecedented rainfall amounts over the past 2 months and OKC is on the verge of breaking the record for the wettest May since records have been kept over 100 years ago.
So far Will Rogers Airport in OKC has had 12.85 inches of rain this May and this is second place for the all time wettest May behind May 2013 when 14.52 inches of rain was recored.
Looks like we'll make a run at the record because I see this pattern continuing for at least another 10 days before a change. Check out the rainfall from just the past 30 days from the Oklahoma Mesonet.
Lets talk about the next system coming in Monday night through Wednesday morning. It looks like it's going to rain again. I'm not going to get into the fine details right now but expect a few scattered thunderstorms possible Monday afternoon as a weak front slides in from the north. The air will be unstable Monday ahead of this front so there is a marginal risk for a few severe t'storms Monday with the main threats locally heavy rain, large hail and damaging winds. The tornado threat is low since the upper level pattern is not favorable for tornadoes but you can never rule it out in May.
Here's one of our hi res computer models showing the weather around 4pm Monday afternoon predicting a few scattered t'storms in central Oklahoma along the southward moving front. It's almost what I call a backdoor front since it's coming in from the north northeast.
Now, lets put this computer run in motion and watch the rain / thunderstorms spread over Oklahoma from west to east Tuesday into Wednesday morning. Some severe weather is possible but I'm more concerned with heavy rainfall and flooding this go around. Click here to see the map in motion!
This last map I posted above in the total rain accumulation from Monday through early Wednesday morning. So another storm system with severe weather and heavy rain is on the way. As always these maps are not set in stone and things will change so make sure you pay attention to the weather and check back for updates. Yet, another storm system on track for this coming weekend. Have a great day, Jon
